10/10 uncomfortable things to build extreme confidence but they get progressively more niche. Go 24 hours with zero entertainment, no music, no phone, just your thoughts. Talk to one stranger a day. Doesn't have to be anything deep, just engage a conversation. Record yourself talking for 10 minutes and actually watch it back. Sit alone in a restaurant, with no phone to hide behind, just observe and be present. Say the thing in the room everyone's thinking but won't say. Ask for the discount, the upgrade, and let them say. Give your opinion about things before you've checked if it's safe to do so or not. And get so comfortable being uncomfortable that fear stops being a reason not to do things.
